I searched and read all threads for cracked transmission and a few others and came up empty handed. My problem is that I was leaking a ton of transmission fluid and I thought it may have been a loose drain plug. Upon checking that, I noticed it wasn't the drain plug that was leaking, it was 2 cracks or tears on the far passenger side of the transmission. The cracks are round which makes me think that they were caused from something spinning in the transmission. My question is why did this happen? For starters, my transfer case is shot and when it went, I was traveling about 20mph and then drove the car about 100 feet to my driveway(transfer case didn't lock up). The only other cause I can think of for the transmission cracks is crankwalk. The crank hasn't walked yet but I do/did have one of the tell tale signs of of dreaded crankwalk, when you depress the clutch and the car is in gear, rpms drop because of flywheel engagement(there is 116,000 miles on the car). I have attached a pic of the cracks, might be a little hard to see but they are there. I just need some help determining what to do now. 6-bolt swap, new tranny and transfer case or something else?
